[jira] [Comment Edited] (PDFBOX-2774) Can't encode Euro in field
with WinAnsiEncoding
[ https://issues.apache.org/jira/browse/PDFBOX-2774?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14512138#comment-14512138 ]

--------------------------------------------------------------
The fonts used in the fields specify WinAnsiEncoding, however that encoding does not contain the Euro symbol *[edit: actually it does - more research needed]*, which is why there is an exception. We could do something like overwrite Encoding in the Font's dictionary but we should probably look at how Acrobat handles this case first. This is a problem specific to filling out form fields.
Note that the two "small tests" do not reproduce the problem, they're calling quite different methods which happen to result in the same exception because PDTrueTypeFont.loadTTF creates a font which uses WinAnsiEncoding, while PDType0Font.load supports full Unicode. There's no bugs in those examples and this behaviour is expected and not relevant to the form-filling issue which I mention in the previous paragraph.
